According to the tabloid, Skripal called his niece Viktoria on 9 May, the day when Russia celebrates the victory over the Nazi Germany in the World War II, and left a message on her answering machine.
"Hi, Vikulya. This is Seryozha. I have tried to put a call through, but the number was unavailable. Oh well, best wishes on the holiday to you! I wanted to find out how things were with you… Oh well. I am fine, we are fine, Yulya [Skripal's daughter], too," the recording said.
Skripal reportedly called Viktoria earlier this spring after she and her husband got beaten up over a conflict with a former housing bill manager.

Skripal and his daughter Yulia were discharged from hospital last spring several weeks after the two of them were found unconscious in the city of Salisbury. Their whereabouts since then have been unknown.
Earlier this week, the Russian embassy in the UK expressed its regret over the fact that London continues to mention Russia's alleged involvement in the Skripal poisoning without providing any evidence.
